Abstract
An aqueous latex of a poly (beta-hydroxyalkanoate) (PHA) coated on pap er imparted water imperviousness without changing mechanical propertie s. Hot-pressed films biodegraded faster than solvent cast films. The P HA coating on paper degraded totally in activated sludge within 12 day s, leaving the cellulose matrix relatively untouched. Blends of PHA la texes with sodium carboxymethyl cellulose, polystyrene latex, carboxyl ated styrene/butadiene latex, natural rubber latex, and starch powders form satisfactory films at room temperature.
